SPECIFICATION forming part of Letters `Patent No. 240,520, dated April26, 1881.

Application filed October 4, 1880.

improvement is fully set forth in the following specification, referencebeing had to the accompanying drawings.

The object of my invention is to provide a device for sharpening pencilsin as perfect a manner as is possible.

Figure 1 is a perspective view, and Fig. 2.

represents a detail.

A is a case in which are arranged a cutter, C, an inclinedbearing-surface, B, and afpressure-spring, D. The slot E is for thepurpose of inserting the pencil, and the slot F for letting out theshavings. The cutter C is fastened to the case with a screw.' One endof' low the edge of the cutter, enough to make it takeo a shaving whenthe pencil is drawn down the inclined bearing-surface over the cutter.The roughened surface or portion G on the'cutting-blade is for thepurpose of rubp (Model.)

bing the lead point of the pencil to bring it to a fine sharp point.This portion of the cutter or cutting-blade is cut similar to a iile.

To sharpen the pencil, insert the end in the slot E in the case A andpush it forward over the cutting-blade C, and, as it is forced forward,it will raise the pressure-spring D, which will let it move up theinclined bearing-surface B to the stop or end of theineline,

above the cutting-blade C. Then, as the pencil is drawn back and downthe inclined bearing-surface, with the pressure-spring D bearing downupon it and forcing the pencil against the cutting-blade C, it willcause the cuttingblade to take off a shaving, which will pass out of theslot F. The continuous moving of the pencil forward and backward, and atthe same time turning it around in the lingers, so as to bring all ofits surfaces to the cuttingblade, will sharpen it to a point in thecenter on the same pitch as the pitch of the inclined bearing-surface.

What I claim is- As a new article of manufacture, a pencil- Sharpenerconsisting of a case, A, having slots' E and F, pressure-spring D,inclined bearingsurface B, and cutting-blade C, having roughened portionG, all substantially as set forth, and for the purposes described.
